Google Authenticator and iOS Backup Restore

I've got a new iPhone.

I did a full encrypted backup of my old iPhone to iTunes. I reset the old iPhone and gave my old iPhone to my daughter. Then, I restored the backup to my new iPhone. To my surprise, Google Authenticator app was empty.

All my 20+ authenticator sites were gone!

Fortunately I did have a backup device just for the authenticator. I also had screenshots of most authenticator QR codes in an encrypted disk.

So it was not too much of a problem to bring my authenticator codes to my new iPhone.
For sites with backup QR codes the process was easy.
But for sites only in my backup authenticator device, I had to disable 2FA and setup a new one.
During the process, I found 0.1 ETH in a semi-closed Chinese exchange and withdrew to my wallet :)

If I didn't have the backup QR codes and backup authenticator device, it would have been a nightmare.

I'm not sure why Google Authenticator backup was not restored, but it seems I'm not the only one.

If you get a new iPhone, do NOT reset your old iPhone before migrating Google Authenticator.

And make sure you have a emergency plan for everything crypto related.
